Source basis

SONES describes itself as Senegal's public water-asset company and sets out its role in planning and financing urban drinking-water infrastructure. At Mamelles it is the project owner and client across the plant, marine intake and discharge system and associated Dakar network work. Toyota Tsusho identifies its consortium as the design-build contractor with a two-year operating obligation; TPF provides construction supervision. SONES's 12 March 2026 visit confirms an active owner-side site review but does not publish completed discharge works, wet-test results, first compliant water or formal operating release. Those remain separate acceptance gates.
